Does the HomeWizard kWh meter also work without the HomeWizard P1 meter on the HomeWizard Energy app?

All our HomeWizard Energy meters are modular (Standalone). Also that you don't need an extra base station (gateway), hub or bridge. All the HomeWizard kWh meter's ( HomeWizard WiFi kWh meter 3-fase or  HomeWizard Wi-Fi kWh meter MID ) therefore works without using the HomeWizard P1 meter. 

Although we do recommend using this combination for a better and complete overview of your energy consumption.
